Climate Chart of Denver, USA

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

The coolest monthly mean is -3.2 °C in January, while the warmest is 23.1 °C in July. These are averages for each month, not daytime maximum temperatures, so they describe the broad seasonal temperature pattern rather than the range a visitor might experience on an individual day. Across the calendar months, the unweighted mean of the monthly mean temperatures is 9.2 °C; it is not a day-weighted annual average.

Rain

Mean daily rainfall is lowest in February at 0.04 mm/day, and highest in May at 2.83 mm/day. These daily averages help distinguish the months by typical rainfall amount, but they do not show how often rain falls or guarantee dry or wet conditions on a particular day. The unweighted mean of the monthly mean daily rainfall figures is 0.83 mm/day; this is not a monthly total.

Snow

The highest monthly mean daily snowfall is 7.41 mm/day in March. This is an average daily amount, not a monthly total, and it does not establish the number of snowy days, snow depth, snow cover, or skiing conditions. Across the calendar months, the unweighted mean of the monthly mean daily snowfall figures is 3.10 mm/day.

Sunshine

Mean daily sunshine reaches its highest level in June at 12.74 hours/day, and its lowest in December at 7.27 hours/day. These figures describe average sunshine duration, not day length, and can help with broad outdoor-planning expectations without predicting the conditions on any specific date. The unweighted mean of the monthly mean daily sunshine figures is 9.90 hours/day.

Best Travel Time Guide for Denver, USA: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, February is the conditional option in the supplied data, with mean daily rainfall of 0.04 mm/day; this does not guarantee dry days, so it is still sensible to plan for changing weather. The highest mean daily rainfall is in May at 2.83 mm/day, a useful prompt to include rain-ready clothing when planning for that month. Those prioritising cooler monthly mean temperatures may prefer January, whose mean is -3.2 °C. Because this is a monthly mean rather than a daytime forecast, visitors should allow for day-to-day variation when choosing clothing and activities.

For outdoor sightseeing planned around average sunshine duration, June has the highest mean daily sunshine at 12.74 hours/day, while December has the lowest at 7.27 hours/day. Sunshine duration is not day length and does not guarantee clear skies on a particular day, so check forecasts close to travel. Snowfall is most notable by monthly mean daily amount in March, at 7.41 mm/day. This average cannot tell you how many days will have snow or whether snow cover will be present, so it is not by itself a guide to snow-dependent activities.
